IQE lifts 2026 revenue outlook as AI and data centre demand accelerates

What has IQE announced?

IQE has upgraded its full-year revenue guidance after trading during the first half of 2026 exceeded management expectations.

The compound semiconductor wafer specialist expects revenue of at least £64 million for the six months ended 30 June 2026. Strong demand was recorded across all of its core segments, with particularly encouraging momentum from artificial intelligence and data centre applications.

Management now expects full-year 2026 revenue growth of more than 30% year-on-year. That represents a stronger outlook than previously communicated, although the announcement does not disclose the earlier guidance or provide a specific full-year revenue figure.

The group also expects to generate adjusted EBITDA in the low teens of millions of pounds. EBITDA means earnings before interest, tax, depreciation and amortisation, while the adjusted measure excludes certain items management considers non-underlying.

IQE's key trading figures

Measure	Latest update
H1 2026 revenue	At least £64 million
FY 2026 revenue growth guidance	More than 30% year-on-year
FY 2026 adjusted EBITDA guidance	Low-teens £m
Cash at 30 June 2026	£41.6 million
Bank debt	None

There is plenty for investors to digest here, but the central message is straightforward: demand is running ahead of IQE's previous expectations, and management believes the momentum can continue through the remainder of 2026.

AI infrastructure is driving demand

The most important operational detail is the accelerating demand for IQE's Indium Phosphide, or InP, solutions.

InP is a compound semiconductor material used in optical photonics products. Put simply, these products help move and process information using light, making them important components within data centres and AI infrastructure.

IQE says its InP solutions play a critical role in these applications. This positions the group within supply chains serving two prominent areas of technology investment, although the announcement does not disclose the revenue contribution from InP or quantify its growth rate.

That distinction matters. The update provides clear evidence that demand is strengthening, but investors do not yet have the segment-level numbers needed to judge its precise financial contribution or profitability.

Chief executive Jutta Meier said IQE's long-established leadership in InP and other material systems had made it critically embedded in supply chains benefiting from industry trends. She expects these trends to support further progress in the second half.

Growth is not limited to AI and data centres

While InP demand is the headline attraction, the first-half performance appears to have been relatively broad-based.

IQE also reported ongoing strength in aerospace and defence, alongside robust demand for 3D sensing and wireless products. That breadth is encouraging because it suggests the improved performance is not dependent on a single end market.

The company operates across smart connected devices, communications infrastructure, automotive and industrial applications, and aerospace and security. Its products are epitaxy wafers, which are specially engineered semiconductor layers grown on a base wafer and used by customers to manufacture chips and other components.

The update does not provide revenue figures for these individual markets, nor does it disclose customer concentration, order volumes or the duration of current demand. Those details will be useful when IQE publishes fuller financial results.

Why the guidance upgrade matters

An increase in expected revenue growth to more than 30% year-on-year is significant. It indicates that the stronger first-half trading is expected to carry into the second half rather than being treated as a short-lived boost.

The adjusted EBITDA outlook also suggests that the revenue growth should translate into improved underlying earnings. However, the phrase "low-teens £m" leaves some room for interpretation, and the company has not disclosed an exact figure or an adjusted EBITDA margin.

Investors should also note that adjusted EBITDA is not the same as statutory operating profit or net profit. The announcement contains no guidance for depreciation, amortisation, exceptional items, finance costs, tax or earnings per share.

Even so, pairing faster revenue growth with positive adjusted EBITDA expectations gives the update more substance than a revenue upgrade alone.

The cash position provides reassurance

IQE reported cash of £41.6 million at 30 June 2026 and remains free of bank debt.

That is a useful balance sheet signal. A bank-debt-free position reduces exposure to interest costs and lender restrictions, while the cash balance gives the business financial flexibility.

There are still unanswered questions. The announcement does not provide a cash flow figure, capital expenditure guidance, lease liabilities or other potential obligations. It is therefore not possible to assess from this update alone how much of the £41.6 million is available for investment or how the cash balance may change during the second half.

Nevertheless, stronger trading alongside a bank-debt-free balance sheet is a positive combination.

What could support further progress?

The main positives in the announcement are:

• First-half trading exceeded management expectations.
• H1 revenue is expected to reach at least £64 million.
• Full-year revenue growth guidance has increased to more than 30%.
• Demand is strong across AI, data centres, aerospace, defence, 3D sensing and wireless products.
• Adjusted EBITDA is expected to reach the low teens of millions of pounds.
• IQE had £41.6 million of cash and no bank debt at the half-year end.

The breadth of demand is particularly helpful. AI and data centres offer a compelling growth driver, but support from several other markets may make the improvement more resilient.

What should investors watch next?

The main limitation is that this is a concise trading update rather than a full financial report.

IQE has not disclosed its first-half adjusted EBITDA, statutory profit, cash flow, margins or segment-by-segment revenue. It has also not given an exact full-year revenue target, meaning investors cannot yet determine the implied second-half performance in pounds.

Key points to monitor in future announcements include:

• Whether InP demand continues accelerating.
• How revenue growth converts into gross margin and cash generation.
• The exact adjusted EBITDA outcome within the low-teens range.
• Whether strength remains broad-based across the core segments.
• How the £41.6 million cash position develops as IQE supports growth.

A stronger outlook, with execution now in focus

IQE's update is clearly positive. First-half performance beat expectations, the full-year revenue outlook has been raised, and the balance sheet remains free of bank debt.

The strongest part of the investment case presented in this announcement is IQE's exposure to rising demand for optical photonics products serving AI infrastructure and data centres. Support from aerospace, defence, 3D sensing and wireless markets adds welcome breadth.

The next test is execution. Investors will want evidence that rapid revenue growth is producing sustainable margins, statutory profitability and cash flow. For now, IQE has entered the second half of 2026 with improved momentum and higher expectations to meet.
